Abstract: PROBLEM TO BE SOLVED: To provide an aqueous polymer dispersion for a moisture-proof layer. SOLUTION: This aqueous polymer dispersion has, as its dispersed polymer, a radical-polymerized polymer comprising 20-65 mass% at least a vinyl aromatic monomer (monomer A), 30-75 mass% at least a monomer (monomer B) having two conjugated ethylenically unsaturated double bond, and 0.5-10 mass% at least one other monomer (monomer C) selected from the group consisting of α,β-monoethylenically unsaturated mono- and di-carboxylic acids and their ester derivatives, and the quantity of its alkali metal ion GA is not less than 0.5 mass% of the mass of the dispersed polymer, and the pH of the aqueous dispersion medium is controlled to less than 6.

Abstract: An aqueous polymer dispersion with a polymerisate in disperse distribution in a radically polymerized form is synthesized from at least one vinyl aromatic monomer A; a doubly conjugated ethylenically unsaturated monomer B; and a monomer C selected from alpha, beta-monoethylenically unsaturated mono- and dicarboxylic acids or their amide or ester derivatives. An aqueous polymer dispersion with a polymerisate in disperse distribution in a radically polymerized form synthesized from (wt.%): at east one vinyl aromatic monomer (monomer A)(20-65); at least one doubly conjugated ethylenically unsaturated double bonded monomer (monomer B)(30-75); and at least one other monomer (monomer C)(0.5-10) selected from alpha,beta-monoethylenically unsaturated mono- and dicarboxylic acids or their amide or ester derivatives, and their content GA of alkali metal ion, relative to the weight of dispersed polymerisate is ≥ 0.5 wt.% , where the pH of the aqueous dispersion medium is set at a value lower than 6 is new. An Independent claim is included for preparation of the aqueous polymer dispersion by radical emulsion polymerization of the starting monomers A, B, and C in the required ratios for production of the polymer, with setting of the pH of the aqueous dispersion medium at below 6 by addition of a specific amount of aqueous alkali metal hydroxide solution.
